Title: Formation of glaze having partial projection
Inventor: MIYAZAWA OSAMU
IPC: B41J2/335
Filed: 1989-12-22
Abstract: PURPOSE:To enable a high quality glaze substrate which is excellent in printing performance to be manufactured by a method wherein a glazed plane layer is formed on the side surface of an alumina substrate, then the glazed surface other than the part to be projected is ground, and the projected part is heat treated and rounded. CONSTITUTION:After sticking Al2O3-BaO-B2O3-CaO-SiO2 glass powder uniformly onto a ground alumina substrate 1 with a spray, a smooth glazed layer 2 is formed by baking. Then, parts other than a part wherein a partial projection is required to be formed are ground with a diamond grinding stone, and a rectangular partial projected glazed part 3 is formed on the glazed layer. In that case, the width and the high of the projection can be optionally varied according to grinding conditions. Corner rounding treatment is performed by a heating process of the glazed substrate having respective rectangular partial projections formed by grinding. A shape of the partial projection obtained by this rounding process is rounded 4 by removing corners, and the glazed substrate having rounded partial projections can be obtained.
